Maybe the title isn't as obvious as i want it to be, i wanted to know from people already investing in cryptocurrencies how to decide/research which coin is worth the money and which is not, what does it take for a coin to look successfull, strong code? Dev support? Most importantly, how to decide where to invest rather than taking advice on what to invest into.
The heart of any cryptocurrency can be found in the spirit of its community. Therefore, look carefully at the community.
This is true, which is why I'm partial to the big altcoins (doge, Dash, litecoin). All of the other ones have transient communities that are destined for the graveyard. You can actually find merchants who accept doge and litecoin, but who's going to take TRUMP, or WAVES or whatever. No one, that's who. So yeah, community is definitely important.
